IMPROVEMENT IN PRINTING-PRESSBS The Schedule referred to in theseLetters Patenband making parl'. of' 'chev saine.

I, CHARLES D. WnrGnzrmGTo-N l of Fairhaven, in the county of Bristol andState ofZ Massachusetts, have invented certain new and usefulImprovements in Printing-Machines or Presses, of which the following isa specication.

The first part of my invention relates to the combination of tworotating cylinders and two reciprocating type-beds, combined andembraced in the same machine in such a manner that a sheet of paper, orother material, maybe printed upon both sides at one passage through themachine. c

The type for printingon one 'side of the 'paper is placed upon one ofthe reciprocating beds, said bedi receiving an impression from one ofthe rotating cylinders; and the type for printing upon' the other sideof the paper is placed on the second bed, the impression being given bythe second cylinder; the object of this part of my invention being toconstruct a printing-machine in which either type or stereotype may beused, said machine not being'conned to the use of stereotype orcast-metal plates or forms, which must be constructed specially for themachine; the machine embodied in my invention being sc constructed as toallow the use ot' either type or stereotype, also any or all of thexturcs in general use, and not being conincd to specially constructedfixtures, thereby obtaining aprinting-machine plain and simple iu itscon# struction and operation, 'so that any person skilled in the artwill readily comprehend and operate the same.

The second part of my invention relates to thecom-v hination of anoscillating toothed wheel, and two reciprocating beds, by means of tworacks, the teeth of said racks meshing into the teeth of the aforesaidoscillating wheel, one of said racks being attached to cach of aforesaidbeds in such a manner that the oscillation ofthe said wheel shall cansethesaid beds to have a reciprocating motion. c w

In large machines it may be necessary to use a second oscillating wheel,and its two racks, upon the opposite side ofthe machine, for thepurpose-of securing gneatersteadinss and ease of motion to the machine.

This part of my invention further relates to the couibination of saidoscillating wheel, a revolving crank, and a pitman or connecting-rod,for the purpose of transmitting the motion from said crank to theaforesaid oscillat-ing wheel, thereby causing said wheel to oscillate orvibrate, said wheel, in turn, imparting its motion to the aforesaidbeds, causing them to have a reciprocating movement.

The third part of my invention relates to the cornbination of tworotating cylinders and two reciprocating beds in such a manner that theweight of o ne of the said beds shall counterbalance the weight ot' theother said bed, the said beds being in an inclined or vert-icalposition.

The fourth part of my invention relates to the combination ot' therotating cylinder, (or corresponding part ,in any p'riming-machine`or,press,) which gives the second impression, or causes the second sideot the paper to be printed upon, and an endless revolvingor travelingapron or blanket, composed of any suitable material, the surface ofwhich shall press or rub against. the surface of the aforesaid cylinderin such a manner that the said apron shall, by ,meansV of its contactwith thepaforesaid cylinder, absorb or wipe oli" from the Asurface ofsaidcylinder (or corresponding part in any printing-machine or press)all ink'that may b'e offset upon said cylinder, from the Aside of thepaper that was iii-st printed, while'the second side is being printed; Ido not wish to confine -myselito the endless apron alone; rotatingrollers may be used instead. The iifth part of my inventionA relates tothe conibination ofthe nippers or fingers that grasp the paper andconline it ,to thev cylinders, and cushion or padholder ,'and the rod orshaft that operates the nippers,

in such a manner that, Vwhen the aforesaid nippers are moved along therod orshaft, the cushion or pad-holder shall be moved atthe same time byone and the same operation, thereby rendering it very easy andconvenient to adjust-the nippers and cushion-holders upon both of theaforesaid cylinders.

Having explained the nature and objects of my iuvention, I will now givea general description of the machine, and the operation of itsseveral'parts, by referring to the accompanying drawing, the'sameletters and figures referring to the same parts in each figure of thedrawing.

Figure 1 is a perspective view of the machine embodying my invention,part of the feed-board repre-l sented as broken away to show partsbeneath it.'

-Figure 2 is a side elevation, showing those parts that operate therotating cylinders and reciprocating beds, also seen in iig. 1, anddesignated by the letters J K K', F Fl F2; also, the endless apron, forremoving the offset ink from the aforesaid cylinder;ralso, thedelivering-tapes and pulleys.

Figure 3 is an end elevationof that part of one of the cylinders whichholds the nippers thatgrasp the paper and confine it to said cylinders,the cushion or pad-holders, and the rod or shaft that operates thenippers; said nippers are also seen at thetop of the cylinders iniig..1. l

Figure 4 is 'a plan of the same.

Figure 5- is a plan of the cushion or pad-holder, the nipper being takenaway.

A A, ig.1, are two side frames, which should be substantiallyconstructed to support and resist the strain and vibrations of theoperating parts.

B Bl Bz B are the cross-ties or girts which connect the side frames A Atogether, yand also suppoxt the ways or tracks C O, in whichthetype-beds D D slide, also forming part of the frame of the machine.

M is the driving-shaft, which is rotated by any suitable device. 4 j Lis a crank, whichreceives its motion from the shaft M.

teeth engaging with the teeth of theracks K K, said,

racks beingsecured to the type-beds D D',`the wheel J being caused tooscillate by the crank L, and pitman I imparts its motion, to the racksK K', and to the type-beds D D', causing them Vto have a reciprocating imovement in alternate directions, one of the beds going up and the othercoming down, and 'vice fvcrsa, thereby causing the beds D D' to travelback and forth under the impression-cylinders E E'.

N N' are toothed racks, which are secured to the type-beds D D', and arecaused to reciprocateby said beds. The racks N N are immediately behindand in fthe same plane of the racks K K', fig. 2.

The racks N N' engage with the teeth on the perimeters of the wheels F1F, and impart an oscillating motion to the said wheels F1 F2, causingeach to make one-half of a revolution. Said wheels Fl F2 rotate looselyo the shafts s s, iig. 2, of the impression-cylinders E E.

The wheel F2' on the shaft sof thecylinder .E also engages with thewheel l on the shaft s of the cylinder E', and imparts an oscillatingmovement t0 the said wheel E, which rotatesloosely on the shaft s.

D D' are two type-beds, upon 'which the type or forms to .be printedfrom are secured, and whichpass back and forth under theimpression-cylinders E E'. Saidbeds D D' are connectedl with each otherby the wheel J, fi'om which the said beds derive their motion; and byYwhich it will be'seen that the weight of one of the beds counterbalancesthe weight of the other hed,thereby causing the aforesaid 4beds to moveup or down with the same ease and without jar. l

E E are two impression-cylinders, upon which the paper. to be printed isplaced.

The cylinder'E gives the impression which prints v the irstside of thepaper, and E' the cylinder which gives the impression for printing thesecond side of the paper.v

As the type-beds D D' move downward and under the cylinders E E', thesaid cylinders rotate in the same direction, and carry the paper betweenthe surface of said cylinders and the face of thetype, and causes thepaper to receive the ink from the type.

I will now describe the manner in which the impression-cylinders E E'are rotated by referring to fig. 2 ofthe drawing.

rPhe oscillating wheel J receives its motion from the crank L, fig. 1,and imparts a reciprocating movement to the racks K K and beds D D',they, in turn, imparting -the same movement to the racks N N', saidrackscausing the wheels Il" Fz to oscillate one-half of a'revolution,and the wheel F2 causing the wheel F to perform one-half of a revolutionat each movement of the wheel J'.

As the bed D passes down in direction of the arrow, under the cylinderE, the rack N being secured to the bed D, causes the wheel FZ to rotateone-half of a revolution in the direction of the arrow, which carriesthe cylinder E in the same direction by means of the spring catch orlatch X, in the wheel F2, engaging with and pushing against theprojection X2, `which is secured to the cylinder E; also, the wheel F2at the l same time causes the wheel F to make one-half' o f a`revolutiomsaid wheel F causing the second cylinder E to make one-halfofa revolution, by means 'of the spring latch X of the wheel F engagingwith and vpushing against the projection Xl of the cylinder E',

the cylinder E then remaining stationary until the next downwardImovement of' the bed D, by which it Awill be seen that the'v cylinder Ehas anintermit-tent motion. y l

When the bed D commences its upward movement the motion of the rack N1,the wheel F, wheel F, is reversed. XVhen the wheel F? has performedone-half of a revolution yin this 'direction the latch X engages withthe projection `X3 ofthe cylinder E, Aand is then ready to give the saidcylinder another halt' of a rev lution, as the bed D moves dowuwardinthe direction of the arrow again. Thebed D', being connected with thebed D by means of' the wheel J, performs a downward movement while thebed D is moving upward.

The rack N, being carried down by the bed D', imparts its motion to thewheel F1, causing said wheel to perform one-half of a revolution indirection` of the arrow. The wheel F1, by means of the latch X, engagingwithand pushing againstthe projection lX4 of the arm G, which `issecured rigidly to thelshaft s of the cylinder E', causes the saidcyelinder E to make onef of a revolution. i

It will bessen by the above that the first half revolution of` thecylinder E is derived'from the downward movement of the bed D by meansof the rack N', the wheel F2, and the wheel F.

The cylinderl E', therefore, has a continuous rotation, .one-half of therotation being derived from the bed D, and the second half rotation fromthe bed D'.`

It, fig. 1, is the fced-board, from which the paper is fed to thecylinder E of the machine.

O O' Of O are the nippers which grasp the sheet and confine it tothecylinders while it is being printed upon.

O O O O are the cushion or pad-holders, an elevation of the 'same beingshown at fig. 3, and a plan of the same at fig. 4, and detached plan ofthe cushionholder aty fig. 5;

The nipper O', in figs. 3 and 4, is constructed similar to those ingeneral use.

Said nippers require to be mpved back and forth along the shaft P, forthe purpose of accommodating various' sizes of' paper.

In all machines heretofore constructed, the nippers O O'Q' O' aresecured to the shafts P P, and

vthe cushionor padholders O O 0 O secured toa second or supplementaryshaft, thereby causing greater complexity, bo'th of construction andoperation, said Ynippers and cushion-holders being entirely independentof each other.

In order to adjust any one of said nippers and its cushion-holder, twoseparate operations are required, thereby causing trouble and a loss `oftime to set the nipper, so that itv shall strike the cushion in thepropel' place.

In my invention it will be seen that, by loosening the set-screw vn,figs.v 3 and 4, both nippel' and cushion-holder are moved along theshaft P by one and the same movement, thereby allowing them to beadjusted with ease and facility.

O, figs. 3' and5, is the cushion-holder,- of which 1 is the cushion.

i is a' projection or tongue on the outer end of said Vcushion-holder,said tongue t fitting into and sliding in the groove fi ofthe cylinderE.

I do not confine myselfto the precise arrangement of the nipper andcushion-holder, as shown by the drawing. The object of my invention isthe combination of the nipper and its cushion-holder in such a mannerthat the operation of either will control the operation of the other.

Fig.5 is a plan of the cushion-holder, showing the manner of itsconstruction, 1 being the cushion, which` by the nipper, which issecured bytheset-screw a. A

By moving the nipper the holder is also moved.

As has been shown'in the foregoing description, the cylinder E has anintermittent rotation.` Said cylinder istherefore, provided with twosetsof nippers, one` set, O' O', seen in iig. 1, 'lhe other set is directlyopposite, upon the under side of said cylinder E, (not shown in thedrawing,) each set of aforesaid nippers grasping a sheet of paperalternately.

As has also been shown in the foregoing description, the cylinder E hasa continuous rotation, and is, therefore, provided with but one -set oflnippers, seen at the top of cylinder E', iig. 1. Said nippers grasp thesheet of paper and take it from the cylinder E.

Fig. 1,'j` is a tumbler, which turns the nipper-shaft P. Eachnipper-shaft is provided with a similar one.

S is a pin which the tumbler f strikes against, said tumbler turningover, and thereby closing the nippers. There is a similar pin at thepoint where the nippers 'are opened, to release the paper, (and not,shown in the dra-wing.) .The cylinder E is also similar pins S.' v

' The above manner ofoperatingthe nippers is adevice commonly used, andwhich .I vdo not claim as part of my invention.

V V1 V2, fig. 2, are the livering-tapes run.

a' al a? are the delivering-tapes, which may be -extended any desireddistance by means of pulleys,

W W are cylinders or rollersV upon which the endless apron or belt Yrevolves.

Said vapron is pressed against the cylinder' E by the roller W.

The roller W may be also 'used without and independent of the aforesaid.apron vY.'

Having described each part of my invention, and its operationseparately, I will now describe the 'operation of the machine complete,and as a whole.

The paper to be printed is placed at the forward provided with pulleysupon which the deend of the feed-board R. It also projects over-the*-cylinder E. y

The machine is then putin motion byrotating the shaft' M, by which thecrank L is `also caused to rctate, and, through the lpitman orconnecting-rod I, causesA the wheel J to oscillate. The said wheelJimparts' a reciprocating movement to the type-beds- Asthe bed D beginsto descend, the wlieelF2 begins to rotate. The spring-latch X of saidwheel engages with the projection X2 of the cylinder E,and causes saidcylinder torotate. The tumbler f comes in contact with the pin S, andcloses the nippersO' 0 upon the paper on the feed-board It. The cylinderE makes one-half of a revolution, and

carries the forward edge of the paper nearly to the type on the bed D,(at the same time the cylinder E makes one-half of a revolution, bymeans of the wheel F2 engagingwith the wheel F, the latch X of thevcylinder E,) and carries the paper between the vsur-V face of saidcylinder and the face of the type on the bed D, and causes one side ofthe paper to be printed upon, (at the same timethc second set of nippersof the cylinder' E grasps another sheet of paper from the feed-board B.)The cylinder E then remains stationary, whilethe bed D again makes anupward movement, the nippers O 0', which holdthe-forwardedge of thepaper, then being at' the positionag.' 2, at which position said nippersrelease the paper, which is selijzed by the nippers of and takenonto thecylinder P'.

While the bed Dis making aforesaid upward movement, the bed 'D' at thesame time makcsa downward movement, and causes the cylinder E' to makeone-halt` of a revolution, (by means 'of the wheel Fl,

is secured to the shaft s of the'cylinder E',) carrying the nippers 0'O' to the position t opposite the position t'of the 'cylinder E. The bedD' then makes an upward movement, the

nippersof the cylinder E take the paper fromthe nippers of the cylinderE, causing the side of the paper already printed to be inside andagainst the surface of the cylinder E', the side of the paper not yetprinted being on the outside, ready to take an impression from the typeonthe bed D'.'A The cylinder E' then makes one-half of a revolution, (bymeans of the downward movement of the bed D, which causes. thewheels'l!12 and F to rotate, andv the latch X of the wheel F pushingagainst the projection X1 of the cylinder .EQ ng. 2,) and carries theforward edge of the paper nearly to the type on bed D'. l

The bed D' thenmakes a downward movement, and causes the cylinder E tomake another one-halt" of a revolution, (by means heretofore described,)and carries the paper between the lsurface of said cylinderand the faceofthe type on the bed D', thereby causing the second side of thc paperto be printed. When the cylinder E carries the forward edge ofr thepaper opposite the roller V, fig. 2, the nippers'are caused to open, (bymeans already described,) and the paper is conveyed over said roller V,(by means ot' the tape al, whichpasses around the cylinder E and overthe rollers V V1 V2, and under the roller W, andl agvain onto thecylinder E,)A and along the ltape a2, between the rollers Vl and V2, inthe direction ofthe line l).

The manner of conveying the paper through the -`machine and thearrangement of the delivering-tapes are comm'on devices, therefore I donot claim them as 'part of my invention.
